Synthesis tool using a modified AIGER based format as input. The format allows for 1-streett specifications. Described here, and is derived from SYNTCOMP format.

• pycudd library: http://bears.ece.ucsb.edu/pycudd.html (tested with version 2.0.2)
• swig library: http://www.swig.org/ (tested with versions 2.0.11)
• (probably) python2.7 headers
• checked on Ubuntu 14.04 and 16.04
• testing script run_func_tests.py requires spec-framework and IIMC if you want to model check the results

Run

./configure.py

It will create config files config.py and setup.sh -- update them according to your setup.

File setup.sh puts cudd library into your LD_LIBRARY_PATH:

export LD_LIBRARY_PATH=/path/to/pycudd2.0.2/cudd-2.4.2/lib

So, run it (. ./setup.sh) before using aisy.py.

Then compile AIGER parser, by running

aiger_swig/make_swig.sh

./aisy.py -h

If you get

ImportError: libcudd.so: cannot open shared object file: No such file or directory

then run . ./setup.sh.

To run tests without model checking of the models synthesized:

./run_func_tests.py

To run it with model checking:

./run_func_tests.py --mc

(from the tool root directory)
